Subject Re: What's the blessed way to compile REEF.NET right now?
Date Tue, 18 Jul 2017 21:46:24 GMT
Yesterday Julia asked me if we should remove the string and I said yes
because it appeared that nuget was figuring out the dependency, but it was
not as I had added it to 10.x json entry to wake for one of my other pull
requests. So this is my fault.
